1.5L PET bottle visual defect detection machine based on AI deep learning technology, it is full automatic in-line inspection for the PET milk bottles, like the black dot, crack, deformation, ovality, etc. This machine are adopted at detecting defects with complex characteristics. They can address complex surface and appearance defects, providing the most advanced level AI visual inspection machine and the customized AI system solutions of visual imaging, computing power, algorithm, and automatic control software for various sub-industries.It can be installed with the existing production lines and inspect the objects in-line, the inspected bottles are detected through the material sorting system to ensure the oriented position, which is the same direction and evenly distributed, and then the inspected objects enter the vision system to take full area images, and transmit the image data to the software system to identify the objects, it will automatically reject the defective product and counting the qualified ones automatically.
